Quite a sensationalist title. Perhaps I don't fully comprehend the ins and outs of high end jewelry but the pictures felt like over the top items that might be costume jewelry or might be part of Liberace's estate sale...
These are actually examples higher-end jewelry (real gold and diamonds, although mass-manufactured): http://slimages.macys.com/is/image/MCY/products/5/optimized/...

This is another example of pave with better coverage: http://i00.i.aliimg.com/wsphoto/v4/1383610324_1/Full-stones-... Still, uniform diamonds, each one is interchangeable with every other one. In the JAR jewelry, it's obvious that each diamond was carefully chosen for its place, the settings are harder to do, and there's more color variation throughout.
There's obviously more to it than that, but that might be a good thing to look for when you're considering the artistry that went into these. Also, keep in mind, they're not really meant to be worn like day-to-day "jewelry" jewelry we're used to seeing around. They're more like tiny pieces of elaborate gemstone art.
